Effects of white-tailed deer on populations of an understory forb in fragmented deciduous forests
Article Abstract:
Effects of grazing by white-tailed deer on populations of an understory forb, or Trillium species, have been studied in fragmented deciduous forests in the Big Woods forest ecosystem in southeastern Minnesota. An exclosure experiment, transplant experiments, and comparisons of Trillium populations at different study sites showed no significant changes for current-year herbivory on reproduction in the year after. Deer preferred large plants in a reproductive stage. Flowering rates at one site with high overwinter deer densities for at least the five years before show indications that cumulative effects of grazing over some years can cut down reproduction in years thereafter. Changes in landscape structure and deer numbers have changed relationships between plants and deer in such a way that grazing can bring on local disappearance of such sensitive forbs as Trillium. Long-term management of deer at low densities seems to be required for conservation and restoration of fragmented eastern North America forests.

Recovery patterns of understory herbs and their use as indicators of deciduous forest regeneration
Article Abstract:
Recovery patterns of vegetarian following up to 35 years of forest regeneration in restored former cottage and road sites at Point Pelee National Park, Ontario, Canada is studied to judge the vulnerability of the understory herbaceous species. Findings reveal that there were no major differences in the diversity of native plants between restored and relatively undisturbed reference sites.

Effects of forest roads on understory plants in a managed hardwood landscape
Article Abstract:
The distributions of understory plants and their relationships to unpaved forest roads in a northern hardwood landscape in the Chequamegon National Forest, Wisconsin (U.S.A) have been examined. Fifteen exotic species were found all of which were detected on the roadside.
